Application filed August 11, 1906: Serial 1%. 33 L151.

To all whom, it inc-y concern:

Be it known that I, GUY R. PRIDE, citi zen of the United States, residing at Jeolo sonville, in the county of Drivel, State of Florida, have invented new and useful. linorovsments in Apparatus for Extracting Turpentine from Wood, oi which the iollow- I ing is e specification. My invention relates to devices for extracting turpentine and oth r produc ts from wood by subjecting the wood in e closed. retort to the action of steam, and has for its main ohject to provide certain improvements in the construction of the some whereby the steam may be introduced to the carrier at the hot tom thereof and yet be forced to pass downword through the wood contained in said carrier.

My invention also embodies certain other novel features, as will he hereinafter more definitely pointed out and claimed, reference being had to the accompanyingdrawings, in which Figure 1 is s side elevation, partly in seetion, of my improved retort and wood-car-- .rier. Fig. 2 is an enlarged detail View of the connection between the lid of the retort end said retort and also the contact between the carrier and the retort. Fig. 3 is a detail supply pipe, and their connections, taken at a right angle toFig. 1.

Similar numerals of reference denote corresponding parts in all the views.

In the said drawings the reference-numeral 1 denotes the retort, the some being open at its'top and havingits curved bottom 2 riveted steam-tight to its sides at 3, the whole being supported by the framework 4.

Tapped centrally throiwh s stuffing-box 5 in the bottom 2 is s stearn-edi'nission ip-e e, the some being connect-ed by on angu er fitting 7 with a steam-s11 ply pipe 8, leodingto a source of steam-supp j. A yoke Q, fixed to the under side of the bottom 2 of the retort, carries a screw-rod 10, contacting with a shoulder 7 a on fitting 7 to adjust the steampipe 6 verticellyges best shown in Fig. 3.

Further detailed description of these parts, however, is omitted, the same being separately described and claimed in an application. filed of even date l'icrewi 330,152, it being essential only to the present invention that there shall he a vertical odjustnient of the steam-admission pipe 6.

View of the steam-admission pipe, the SlZQEtHr Also tapped into the bottom 2 of the retort is e 1pc ii for carrying off the vapor laden with the turpentine and. conducting it to the condenser.

The retort 1 at its open top is provided cxteriorly with an annular rim 12,.riveted steam-tight thereto and provided at interfva-ls with pairs oi lugs 13, carrying bolts 14,

upon which are oivoted screw-holts 15. A

lid or cover 16 for said retort has riveted thereto at its edge ring 17 that is recessed J 1 intervals corresponding with the or Y-bOlhS 15, which letter are adapted to no turned no into said recesses and by means nuts 18 Firmly unite said cover in order to make the joint between said ports steem-tight, I form the some by an an nulsr pecking 19, located in on annular groove in the under $1 e of the ring 17, with which :1 rih 20 on the rim 12; of the retort 1 crises-es.

The carrier for the wood to be treated consists of e. cylindrical body 21, having fixed centrsllytherein at its bottom :1. steen1-pipe 22, the some extending upwardly to 'prscti- 8o cally the top of said carrier, Where it terminot in e 23, from which radiate horizontal pipes 24. carrying at their outer ends downwardly-extending perforated j ipes 25, said pipe 22 being also pcrl omted. I'or one-third of its length from itsupper end. The bottom of the carrier is-provided 061% trelly with a. fitting 26, "that receives the lower end of pipe 22, and is recessed at 27 on its under siaie ShfiMlPMiInlSSiOH pipe 6, a suitable packing ring 28 of reietively broad area being insert ed therein,egeinst rhich therelatively liar row upper edge 29 of the steanredrnission pipe 6 abuts when said carrier-is located in position in the retort 1. Said ceirricr is prcvid Ll at its upper edge with an annular-ring 30, downturned exteriorlyto rest on a packiug-ring 31, located between the upper edge of the retort l and its rim 12, thereby form- I ing s. steeni-tight joint at this point between sin. carrier and the retort The bottoin oi'- the carrier is formed semicircular downwordly-opning sections normally retained in catches and being provided with :1 series of openings 34 for the escape therefrom of the vapor, said openings each hevihg located thereover on iniperforate plate 35, supported. st 2; distance above its of two 32,

and retort. 7c

about 8 5 to receive the upper end of o their closed position by opening by. series of I10 bolts 36 and having a foraminous screen 37 passing around said bolts and filling the space between said plate 35 and the carrier-bottom.

Further detailed description of these parts,

be treated and is then placed into said retort,

being lifted and deposited therein by a suit-T able derrick or crane, so that its annular ring rests on the packing-ring 31 of the retort.

This will bring the packing-ring 28, located centrally in the bottom of said carrier, against the upper edge 29 of the steam-admission pipe 6, which latter may then be adjusted vertically by means of screw-rod 10 to afford a steam-tight joint between the parts, the weight of the carrier and its -load being ample to produce this result not only at the steamadm'ission pipe 6, but also at the packing-ring 31. Thecover 16 is then placed in position and fastened steam-tight through packing 19 and bolts 15, and the retort and its contents are ready for the admission or" steam. The steam admitted at .the bottom then passes upwardly through pipe 22 and thence through pipes 24 and 25, escaping therefrom through the erfo-rations therein.

ing 31 after ing an annular steam tight joint 7 where between the carrier and the retort 1 at their upper ends, the only escape for said steam and the tur entine-vapor extracted from the wood will e through the openings 34 at the bottom ofthe carrier, said steam passing downward through the wood and after passing out through the openings 34 being.carried off by means denser.

From the above description of the operation it will be seen that I am able to provide a removable carrier for the wood which when located in the retort provides a steam connection withthe-interior of said carrier that may be effected exterior-1y of the retort and at the same time provides for a downward passaglpof the steam through the wood, y the extraction of the turpentine is greatly facilitated. a

- When the action of the steam on the wood is completed, the cover and carrier are re Inoved'and, if desired, a fresh carrier charged with wood inserted, while the first carrier is being emdptie'd by opening its doors 32 and recharge thus obtaining a substantially continuous operation of the retort.

It will be understood that while I prefer to carry off the steam and turpentine through the openings 34 in the bottom of the carrier I do 'not wish to limit myself to said specific construction, the whole object beingto sub- The packof the pipe 11 to the conthrough in a downward direction, which may [be accomplished in any suitable manner.

While have described my invention as particularly'applicable to the extraction of ,turpentine from wood, wherein it is desirable to treat the wdod in large masses, it will be understood that I do not confine myself tov such use as the device is equally applicable to other uses wherein masses of material are to of for other purposes.
